The canopy is not divided into distinct layers; instead,\nthe forest has a continuum of different-aged and different-sized trees. The grouping of trees of various sizes is also\ntypical. Trees at different stages of development enable management measures aimed at continuous cover forestry. In\nuneven-aged forestry, the forest must be harvested often and sparsely enough to maintain the condition and recovery\npotential of small trees and the undergrowth. Transforming a uniformly-aged spruce stand, managed with low thinning,\ninto an uneven-aged structure is slow and susceptible to wind and bark beetle damage.<\/p><p>The stand was established in 1898 by sowing pine and spruce seeds on slash-and-burn land. Between 1923 and 1993,\nseven light thinnings were carried out in the stand. The trees on the sites were measured and mapped in 2023.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-edd8464 elementor-widget elementor-widget-heading\" data-id=\"edd8464\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Marteloscope Punkaharju<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1ccb8a1 elementor-widget elementor-widget-image\" data-id=\"1ccb8a1\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en.jpg\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"Marteloscope Punkaharju\" data-elementor-lightbox-description=\"Marteloscope Punkaharju\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NTU0NCwidXJsIjoiaHR0cHM6XC9cL3d3dy5tZXRzYWJpb3RhbG91cy5maVwvd3AtY29udGVudFwvdXBsb2Fkc1wvMjAyNlwvMDRcL21hcnRlbG9zY29wZS1wdW5rYWhhcmp1LmpwZyJ9\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"599\" src=\"https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en.jpg\" class=\"attachment-large size-large wp-image-5544\" alt=\"Map of two Marteloscope sample plots in Punkaharju, showing tree locations, species, and sizes with color-coded circles.\" srcset=\"https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en.jpg 1254w, https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en-300x172.jpg 300w, https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en-1024x585.jpg 1024w, https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en-768x439.jpg 768w, https:\/\/www.metsabiotalous.fi\/wp-content\/uploads\/2026\/04\/marteloscope-punkaharju-en-18x10.jpg 18w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2d9638a elementor-widget elementor-widget-wd_text_block\" data-id=\"2d9638a\" data-element_type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<p>The sites are part of the international Marteloscope\ndemonstration site network.
